Yogendra Pathak Viyogi (Y. P. Viyogi) is an Indian physicist at Indian National Science Academy. He is specialized in the field of experimental nuclear physics.[1][2][3]
"It is certainly a matter of great pride for all of us to be a part of the discovery of anti-alpha, the heaviest anti-matter to have been seen in terrestrial experiments."
— Y P Viyogi, in Subhra Priyadarshini, Indian scientists in antimatter discovery, Nature India
Early life
[edit]He born at Madhubani in the year 1948.[4] He completed his primary education at his own village.
He received his post graduate degree in physics from Bihar University in Muzaffarpur.[5]
Scientific career
[edit]He joined the 15th batch of Training School Programme of Bhabha Atomic Research Centre, Mumbai in 1971. He was trained in experimental nuclear physics at BARC and at Lawrence Berkeley laboratory, USA. He moved to Kolkata to work at the Variable Energy Cyclotron Centre, a unit of the Department of Atomic Energy and obtained his PhD in 1984 from the University of Calcutta. He was also a postdoctoral fellow at GANIL Laboratory in France from 1984 to 1986. He was Director of Institute of Physics, Bhubaneswar during June 2006 – June 2009. He retired from service in October 2012 as Outstanding Scientist at VECC Kolkata.[1]
Scientific works
[edit]Y P Viyogi has studied projectile fragmentation reactions involving intermediate energy of heavy nuclei at Berkeley. He has been also involved in the study of quark gluon plasma using indigenous photon multiplicity detector (PMD) at CERN in Geneva and Brookhaven National Laboratory in USA. He led Indian group of physicists at the ALICE experiment in CERN.[5][6] In July 1993, Y P Viyogi published an article on heavy ion collisions having title "Ultra - relativistic heavy ion experiments: a perspective" at Pramana Journal of Physics.[7]
In 2011, he was the leader of Indian physicists in STAR experiment at Relativistic Heavy Ion Collider (RHIC) in Brookhaven National Laboratory, USA. There he was involved in the observation and detection of the antimatter helium-4 nucleus or anti-alpha. He is one of the physicists who witnessed the discovery of the heaviest anti-matter known as anti-alpha particle.[8][9]
